because of the nature of its items and its component structure, however, individual items in the psqi are not conducive to validation with modern psychometric techniques such as item response theory (irt) models. the sd and sri item banks assess qualitative aspects of sleep and wake function. individual items from the irt-calibrated sd and sri item banks can be selected to create short forms for assessing sd and sri. item response data for the sd and sri item banks were obtained from an internet (yougov polimetrix) sample and a clinical sample at the university of pittsburgh medical center. 3) compare the cat θ estimates with the conventional test θ estimates as a function of the numbers of item administered in the cat. in order to evaluate the convergent and discriminant validity of the final sd and sri 8-item short forms, short form θ scores were correlated with their corresponding full banks, psqi, and ess.
based on cat simulations for all items of the sd and sri item banks, we estimated θ scores for each respondent from single-item administration to the full-bank administration (i.e., from 1-item administration to 27-item administration for sd and 1-item administration to 16-item administration for sri). for example, the 2-item cat for sd provided a θ score correlation of .95 with the full sd bank, and the 4-item cat for sri provided a θ score correlation of .95 with the full sri bank. we also correlated each of the θ scores from cats with the θ scores based on the 8-item short forms of sd and sri. irt analyses of the promis sd and sri item banks permitted the development of cat and 8-item static short forms of sd and sri. the five criteria for selecting short form items reflected a combination of psychometric and clinical input. taken together, the findings of this paper demonstrate the precision and efficiency that the 8-item sd and sri short forms provide compared with their corresponding full scales and the two commonly used scales (psqi and ess).
findings suggest the potential research and clinical utility of adult versions of promis sleep measures in adolescents. measures used to describe sleep phenotypes are not well developed for adolescent populations, and adolescent sleep research is underrepresented in the literature. promis sleep disturbance and sleep-related impairment item banks were developed to improve self-report regarding the sleep-wake function in adults. in this study, the adult 8-item promis sleep disturbance questionnaire (v. 1.0; 8a) was used to measure self-reported perceptions of sleep quality, depth, and restoration within the past seven days.
as summarized in table 1, the cohort was 44% female, and 80% were non-hispanic caucasian. the casq score was significantly correlated with promis sleep disturbance (rs = .77, p < .001, figure 1) and sleep-related impairment (rs = .86, p < .001, figure 1) total scores in our cohort of healthy adolescents. this is the first preliminary validation of the use of the promis sleep measures in adolescents using both subjective self-reported questionnaires and objective actigraphy data. sleep questionnaire and total sleep time correlations in adolescents. spearman correlations and nominal p-values are shown.
we report on the development of short forms from the patient-reported outcomes measurement information system (promis™) sleep disturbance (sd) and promis defines sleep as a reversible recurrent state of reduced awareness of and interaction with the environment, while wakefulness is an promis sleep disturbance scale. instructions: please respond to each item by marking one box per item. in the past 7 days . . . not a. somewhat quite very., .
the dsm-5 level 2u2014sleep disturbanceu2014adult measure is the 8-item promis sleep disturbance short form that assesses the pure domain of sleep disturbance in individuals age 18 and older. the measure is completed by the individual prior to a visit with the clinician. the promis 6a scale is composed of 6 items developed to assess the domain of sleep disturbances in the past 7 days. the first 2 scale items assess sleep quality, and the following 4 items assess domains of restfulness, sleep problems, and difficulty falling asleep. promis measures can be used in the general population and with adults and pediatric populations with a chronic condition(s) promis measures promis item bank v1.0 – sleep disturbance – short form 8a. sleep disturbance – short form 8a. please respond to each question or statement by marking one the promis domain framework (see ) is drawn from the world health organization’s framework of physical, mental, and social health, .
